Code Issues Proposed changes

Add support for CMR 

Although not a typical deployment scenario the ceph-mon charm will
support cross model relations.  To use this feature the local unit
name must be exposed on the relation so that the ceph-mon charm
can target broker responses back to individual units.

Juju obfuscates this to a remote-UUID label so the normal use
of the hookenv set remote unit does not work correctly.
